Multiple Album Covers

[Sparky2114]

I'm am in process of converting all CD's to FLAC. 90% of collection is compilations of 50's-60's R&B. I am using MP3tag to edit each tune. I also am entering 45rpm image as album cover for each entry. There are tunes that were on several labels and I am entering all I find into MP3tag's data base. Some tunes have up to 6 entered labels. When playing back the only album cover (45 RPM copy) displayed is the one in the first on entered. How can I display multiple album covers (45s) for each tune
